今天新入职的小伙伴找我帮他看个问题，同样的springboot工程，同样都是用idea，在我们的电脑上启动正常，但是在他的电脑上就是不行，直接报错：java.lang.NoClassDefFoundError: javax/servlet/ServletContext，开始以为是没编译好，但是重新编译之后依旧不行。
详细错误信息如下：

在网上查了一下，看到很多人提到pom文件中的jar包scope作用域问题，将scope设置为provided时，在打包时是不会被打进去的，而我们的工程中，由于要使用外部tomcat容器，所以屏蔽掉了springboot内嵌的tomcat。
但是当时觉着跟这次的问题不相关，也就没有怎么太在意，后来，同事换成eclipse之后，竟然把项目启动起来了。。。
看起来似乎是工具的问题，我就顺着这个方向继续查原因，发现在idea的“Edit Configurations”菜单中是可以进行设置maven的这个scope作用域的。
如下图所示：
红框所示之处，勾掉了之后，provided就不会生效了，运行时就会找不到依赖的jar包。
我赶紧跑到同事电脑上一看，点开之后却怎么都找不到上图红框中的设置，又是一番折腾，发现他的idea版本是2016，而我的是2020了。
上述就是小编为大家分享的低版本idea中SpringBoot项目启动失败后提示找不到 javax/servlet/ServletContext类该怎么解决了，如果刚好有类似的疑惑，不妨参照上述分析进行理解。如果想知道更多相关知识，欢迎关注亿速云行业资讯频道。
